The stronger you get the fewer reps you'll be able to do. You'll get to a point where you get one rep and that's it. Not to mention unless you've really mastered the lifts going to failure in the 85-100% range isn't exactly the best idea; hell, even when you've mastered the lifts it isn't that smart to do often. Not to mention for deadlifts if you try that your CNS will get so trashed it isn't funny.
You could try clusters if you like that kind of balls-to-the-wall approach. Christian Thibaudeau has some awesome articles on T-Nation about them. I've used them for a short inter-meet cycle and they worked. You start at something like 90% and hit singles taking 30 seconds in between each single until you fail. I usually got somewhere between five and three. Oddly, I found it works best for deadlifts because I pull conventional and there's very little setup. For squats I found it best just to go rep, wait, rep, wait without racking. For bench I set up for the first rep and then just racked and unracked while doing my best to keep my arch.
